If there is anybody who sees Indian domestic news and/or articles, could you tell us whether there is any political impetus there to start spraying climate-modifying aerosols at high altitudes regardless of effectiveness and/or international opinion, or if it's completely outside of the Indian overton window?

Nope. The hot weather is off the news cycle and the top news is political. https://www.ndtv.com/

Cities section does have it.

Instead of relying solely on air conditioning, which often adds to greenhouse gas emissions if run on fossil power, there are a number of passive solar design strategies that work without additional energy: - Solar chimneys draw cool air in when it’s sunny via pressure differential - Building orientation along with natural shading from deciduous trees prevent excessive solar insolation heating the building - Building…

Somehow this has been lost over the years. I can especially see this in Zürich Switzerland where new office buildings being built are awful and there seems little thinking about temperature. Everything is managed by complex air systems to move air from one area to the other. On the other hand you go into a 200+ year old building and you notice it's cool in summer although there is no air conditioning. The building is…

As someone who was in Europe for one of the heatwaves of recent years, and whose appartment was in one of these older buildings designed this ways with thick walls etc., I can attest that this only works up to a point. This design relies on there being cold air for the building to retain. However, in a heatwave it doesn't even get cold at night. The result is your apartment gradually heating over a period of days / weeks and turning into a sauna. It is not pleasant.

By the end of that summer I was dreaming about moving back to north america where air conditioning is much more common in rental units.

"Hilarious" is not the word I'd use. "Dispiriting", "Irresponsible", "Fucked up". I don't understand why we aren't pouring massive amounts of money into public transport. Apparently many people in Western Europe seem to enjoy being stuck in traffic for hours every day. For some reason, company cars are still a thing in Belgium, very nearly everyone working in IT gets one. I can't wrap my head around how stupid this i…

Public transport hasn't solved the problem of "the last mile". How do I get to/from the train station/bus stop? Frequently you still need a car to even get there and then you will need parking - which is often limited and costs a lot. Then there's timeliness. Deutsche Bahn is known for frequently their trains are delayed. In summer, even on the Intercity connections (IC, ICE) trains will be filled to the brim and air…

1. Climate requires that we make some compromise

2. If we used cars less, there is a good chance public transport would have less of those issues you're talking about. It's a vicious circle. Urban planning has been favoring cars for a long time.

How much do these things work when the wet bulb temperature is over 90F?

This would be my concern too. People fail to understand how in heatwaves there ceases to be cold air to move around. Everything heats up. It's brutal.

And here in the western world, people still don't like using public transport and their bikes (when they can). It's difficult to be optimistic, but it seems there is nothing that will truly limit fossil fuel consumption. Maybe some oil producing countries could get in some sort of alliance, and artificially limit the amount of oil they extract, in return for subsidies? Those countries could also put a tariff on oil.…

> people still don't like using public transport Because most public transport sucks, is unreliable, only works at certain hours, is dirty, unsafe, and covers only a small ridiculous amount of space limited to key cities. No wonder. The pandemic will only make public transport less desirable as well.

Yup "nongu" as it is called in southern parts of India is commonly sought after in summer.

Climate change isn't only new record high temperatures. It's also, as described in the article, temperatures consistently being higher than is regular for this time of the year.

How do you tell "climate change" heat waves from "non-climate change" heat waves? I mean "heat waves" are not some recent phenomenon. I mean, any farmer can tell you some growing seasons are really warm, others cold, some very dry and others very wet. No two seasons are the same.

You cannot tell the difference between types of events. However the science says that the frequency increases.

That is what is actually the thing that climate change models say: more exteme weather events.

Climate != Weather

But climate shapes weather.

I would assume it's mostly the thicker walls, at least it was this case in Berlin with older buildings staying cool for a long time because it took months to heat the walls. Then those walls were warm in winter and it took months to cool them down (though it didn't work very well in the last very hot summers that were hot early on)

This is still sometimes done. The newest section of the Freie Universität Berlin campus (the “Holzlaube”) was built so that the inside remains comfortable with no A/C and minimal heating. Thick walls, as you said.

I don’t know how applicable architectural cleverness will be in densely populated cities in the developing world that are threatened by global warming. That seems like an impossible situation.

We need to make public transportation so alluring people want/need to use it. For starters, I think public transportation should be free for the poor, and low middle class. All air travel that uses fossil fuel would would be taxed if you are above middle class. Outlaw the private jets. (It just bothers me to see the Elon, or Saturday Night Fever types jetting off to Ibesa. (Too disenfranchised to check the spelling o…

All those are good things, but in the US, it will be seen as socialist measures.
